本文实例讲述了PHP记录搜索引擎蜘蛛访问网站足迹的方法。分享给大家供大家参考。具体分析如下:
搜索引擎的蜘蛛访问网站是通过远程抓取页面来进行的,我们不能使用JS代码来取得蜘蛛的Agent信息,但是我们可以通过image标签,这样我们就可以得到蜘蛛的agent资料了,通过对agent资料的分析,就可以确定蜘蛛的种类、性别等因素,我们在通过数据库或者文本来记录就可以进行统计了。
数据库结构:
以下为引用的内容:
## 表的结构 `naps_stats_bot`#CREATE TABLE `naps_stats_bot` (`botid` int(10) unsigned NOT NULL auto_increment,`botname` varchar(100) NOT NULL default "",`botagent` varchar(200) NOT NULL default "",`bottag` varchar(100) NOT NULL default "",`botcount` int(11) NOT NULL default "0",`botlast` datetime NOT NULL default "0000-00-00 00:00:00",`botlasturl` varchar(250) NOT NULL default "",UNIQUE KEY `botid` (`botid`),KEY `botname` (`botname`)) TYPE=MyISAM AUTO_INCREMENT=9 ;## 导出表中的数据 `naps_stats_bot`#INSERT INTO `naps_stats_bot` VALUES (1, "Googlebot", "Googlebot/2.X (+http://www.googlebot.com/bot.html)", "googlebot", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (2, "MSNbot", "MSNBOT/0.1 (http://search.msn.com/msnbot.htm)", "msnbot", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (3, "Inktomi Slurp", "Slurp/2.0", "slurp", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (4, "Baiduspider", "Baiduspider+(+http://www.baidu.com/search/spider.htm)", "baiduspider", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (5, "Yahoobot", "Mozilla/5.0+(compatible;+Yahoo!+Slurp;+http://help.yahoo.com/help/us/ysearch/slurp)", "slurp", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (6, "Sohubot", "sohu-search", "sohu-search", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (7, "Lycos", "Lycos/x.x", "lycos", 0, "0000-00-00 00:00:00", "");INSERT INTO `naps_stats_bot` VALUES (8, "Robozilla", "Robozilla/1.0", "robozilla", 0, "0000-00-00 00:00:00", "");
PHP程序如下:
以下为引用的内容:
